Introduction

Seasonal changes bring many beautiful moments, like fresh air, festivals, and new beginnings. But along with these changes, our body also faces new challenges. Many people fall sick during weather transitions due to a low immune system. You may notice frequent colds, cough, fatigue, or infections. These are often signs of low immunity symptoms.

Understanding your immune system function is very important if you want to stay healthy all year. Your immune system protects your body from harmful bacteria, viruses, and infections. But when it becomes weak, your body struggles to fight diseases.

What is the Immune System

The immune system is a natural defense system in your body. It protects you from harmful microorganisms like bacteria, viruses, and toxins.

The main immune system function is to:

Identify harmful invaders
Destroy them before they cause illness
Keep your body healthy and balanced

When your immune system works properly, you rarely fall sick. But if it becomes weak, your body becomes vulnerable to infections.

Here are some common causes:

Lack of nutrients and vitamins weakens your immune system.

Sleeping less than 6–7 hours regularly can damage immunity.

3. Stress

Chronic stress affects hormones and reduces immune response.

4. Physical Inactivity

Not exercising regularly leads to a weak body defense system.

5. Dehydration

Low water intake affects overall body function.
